AUGUSTUS BARLER, OF CHICAGO, ILLINOIS;

OIL-STOVE.

SPECIFICATION forming part of Letters Patent No. 548,739, dated October29, 1895. Application filed May 21,1894. serial No. 511,981. (No 181.)

To an whom it may concern.- Be it known that L'A'UGUSTUS O. BARLER, aresident of Chicago, in the county. of Cook and State of Illinois,haveinvented certain new and useful Improvements in Oil-Stoves; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

My invention relates to an improvement in oil-stoves.

An object is to construct an oil-stove in such manner that fresh airwill be made to enter the drum at points near the wick-tube and becaused to enter the combustion-chamber at points distant from thewick-tube.

A further object is to produce an oil-stove which shall be soconstructed that the oil tank or reservoir will not be unduly heated byradiating heat from the castings between said oil tank or reservoir andthe burner. A further object is to produce an oil-stove which shall besimple in construction and efficient in all respects in the performanceof its functions.

With these objects in view the invention consists in certain novelfeatures of construction and combinations and arrangements of parts, ashereinafter set forth, and pointed out in the claims.

In the accompanying drawings, Figure 1 is an elevation, partly insection, illustrating my improvements. Figs. 2, 3, and 4 are detailviews.

A represents a suitable base adapted for- 'the reception of an oil tankor reservoir of any desired form of constructiomand at the upper portionof said base portion a ring ais secured and adapted to support a rail 0,by

means of interposed legs or supports a said brackets. The ring B'is madewith an inter nal annular plate B, which constitutes the bottom of aheating-drum C, and from said annular plate an annular flange B? dependsDisposed above the rail a" said annular plate being also made with anupwardly-projecting annular flange B in the same plane as the flange BDisposed above the plate B is an annular'plate D, provided at its inneredge with an annular depending flange d, which rests on the plate B,thus producinga space E between said plates, andthe periphery of theplate D is preferably upturned and terminates in proximity to the wallof the drum. The plate B at points in close proximity to the dependingflange B is made with perforations f, through which cool fresh airpasses, said air finding its way to said perforations through the openspace between the oil tank and the heating-drum and through perforationsin the ring B between the rings B and a and between the latter and thering a. After passing through the perthrough opening a between theperiphery of the plateD and the wall of the drum, and.

after passing up through the drum escapes in a highly-heated state atthe top thereof, the

heated air leaving the stove through slots or openings g, made in a capor cover F.

By the construction and arrangement of parts above described it will beseen that the cool fresh air will be made to enter the bottom of thedrum at points in close proximity to the flame, that in passing throughthe space or chamber E between the plates B and D it will become highlyheated, and that it will enter the combustion-chamber of the drum atpoints removed a distance from the flame, thus not interfering in anydegree with the proper combustion of the flame. It will also be seenthat after the fresh air has thus entered the drum it will mix with theheated air from the flame at a proper distance above "the same (becomingsuperheated) and a strong flow of hot air out of the top of the stovewill result; and, again, it will be seen that as the cool air is made topass through or between the castings between the drum and the oiltanksaid castings will be prevented from assuming such temperature as tounduly affect the oil-tank by heat radiating therefrom. The heat of theflame naturally causes a suction of air through the openings fa givingto my improved construction the advantage of a circulating heater.

The drum is hinged to the base portion by means of a hinged connectionbetween one of the legs 17 and a lug at or on the rail a.

At the upper end of the drum 0 a' spider G is located and held in placeby means of rods h, secured at one end to said spider and at the otherend to the plate B, said spider being composed of a disk having openings2' and ribs i, alternating with said openings.

My improvements are simple in construction and effectual in all respectsin the performance of their functions.

Having fully described'my invention; what Iclaim as new,-anddesire tosecure by Letters Patent, is

'1; In a stove, the combination with a burner,

and a drum, ofa plate extending horizontally in the lower end of a thechamber With aspace formed between its outer edge and 'the 'wa-ll ofthe'drum,-and the bottom'of the drumhaving air holes in proximity tothe- 'burner,:sub-

stantially as set forth.

2. In a stove, the combination with a burner,

anda drum at the bottom of which is-located aperforated plate, of aplate disposed-horizontally'above'the perforated plategsaid horidrum,and an air space between said perforated plate and the oil fount ofthe'burner, substantially as set forth.

3. In a stove, the combination with a drum and a burner and opencastings below said drum, of a plate in thebottom of the drum havingperforations in close proximity to the burner for the passage of freshair entering through said open casting, a plate disposed above saidperforated plate so as to produce a space between said plates, saidspace being adapted to permit the escapeof air between the periphery ofthe upper plate and the wallof thedrum, substantially as set forth.

4. In a stove, the combination with a burner and a drum, of-anannularplate at the bot- "tomofsaid drum and having perforations at itsinner edge,- flanges at the inner edge of said plate projecting at rightangles thereto, I an 'annu'lar plateidisposed above the first-'mentioned' plate and having "an annular-da pending flange restingthereon,=said plates -'-being- 'disposedso as to leave a space betweenWitnesses:
